Case Study – Fire Door Lock Fitting

A recent customer contacted Owen the Locksmith after a routine fire safety assessment flagged a critical issue: a wooden fire door had failed because the existing lock hardware was not compliant for the door’s fire rating.


The Problem:

The assessor’s report highlighted that the door required an FD30-compliant locking solution, specifically:

  • FD30 Euro-profile thumbturn mortice locks (to enable secure locking and safe internal escape)
  • Intumescent lock protection fitted behind the lock and hardware to help maintain the door’s fire integrity during heat exposure

Without the correct lock case and the required intumescent protection, the door could not be signed off as compliant.

What Owen Did:

Owen attended the site and completed a compliant upgrade:

  • Supplied and fitted 2 x FD30-rated euro thumbturn mortice lock suitable for the door and its use
  • Installed intumescent lock protection kits correctly positioned to protect the lock case and maintain the door’s rating
  • Ensured the lock operated smoothly, aligned correctly, and provided reliable escape operation from the inside
  • Left the door closing and latching properly, with clean, neat finishing around the lock area

The Result:

The door was brought back to a compliant standard with the correct FD30 lockset and intumescent protection, improving both fire safety and day-to-day usability. The customer was able to present the updated installation as part of their fire safety documentation and move toward sign-off.
